i'm looking for a elk rifle for my girlfriend the biggest game it will see use on is elk but i need as little recoil as possible, i'm looking at the 7mm-08, 308, 270 win, or 270 wsm. which would have the least recoil but still have the power to knock an elk down. i have experience only with the 270 win and am fearing it may have to much recoil for her.
